EASY CONTOUR APP INSTALL
With that being said, I’m ready to install Contour in my Kubernetes cluster. Development and support efforts for the future Gateway API.High performance (also thanks to Envoy).Support for dynamic configuration (thanks to Envoy).Developed as a Kubernetes-first ingress controller.There are many out there, but Contour is my favorite for a few reasons: So now we know why we might need an ingress controller, the next big question is: Which ingress controller should I use? Great question. Now your external traffic will flow through a single load balancer into your ingress controller, which will take ingress configuration to determine which service to forward the traffic to. Once we add an ingress controller into our cluster, the flow of traffic now changes to something like this: There are many different ingress controllers out there, but they mostly fulfill the same requirement: To simplify ingress traffic to your Kubernetes cluster and to provide capabilities and benefits for more sophisticated networking scenarios.

This is where an ingress controller can help. Once you start getting into more complex requirements, you will have to design your own solution.Īs you can see, the external load balancers supporting this configuration can get to be a lot.

This approach can only supply simple scenarios.This is not a trivial task to setup, much less maintain. TLS termination has to be handled at your application pods.Your administration and maintanence of your cloud resources is also magnified, because you will likely have multiple load balancers to deal with.This approach can get expensive very fast. The more applications you have, the more load balancers you need.In fact, a common approach is to just create a service of type LoadBalancer for your application pod(s), and have your favorite cloud provider provision the necessary infrastructure to get traffic to your application.īut, this can lead to a handful of problems: Ingress controllers are surely not a requirement to get user traffic from external to the Kubernetes cluster to your pods running inside. Before we go into ingress, though, let’s take a step back and look at what it is like without ingress. Both Contour and Envoy are CNCF projects.īefore we start diving into Contour specifically, let’s talk through ingress a little bit. Contour is a high performance ingress controller based on Envoy, a layer 7 proxy. This is where we can start to plan for ingress. And on top of that, user traffice from external the Kubernetes cluster can be even more difficult. There are many challenges when working with Kubernetes, and one of the most common scenarios is getting user traffic to your applications.
